AREA
Tells where hazards
may occur.
Spray Area /
High Voltage
Equipment
LN-9282-14
HAZARD
Tells what the hazard is.
Electrical Discharge
There is a high voltage device
that can induce an electrical
charge on ungrounded objects
which is capable of igniting
coating materials.
Inadequate grounding will
cause a spark hazard. A
spark can ignite many coating
materials and cause a fire
or explosion.
SAFEGUARDS
Tells how to avoid the hazard.
Parts being sprayed and operators in the spray
area must be properly grounded.
Parts being sprayed must be supported
on conveyors or hangers that are properly
grounded. The resistance between the part
and earth ground must not exceed 1 meg ohm.
(Refer to NFPA-33.)
Operators must be grounded. Rubber
soled insulating shoes should not be worn.
Grounding straps on wrists or legs may be used
to assure adequate ground contact.
Operators must not be wearing or carrying any
ungrounded metal objects.
When using an electrostatic handgun, operators
must assure contact with the handle of the
applicator via conductive gloves or gloves with
the palm section cut out.
NOTE: REFER TO NFPA-33 OR SPECIFIC
COUNTRY SAFETY CODES REGARDING
PROPER OPERATOR GROUNDING.
All electrically conductive objects in the spray
area, with the exception of those objects
required by the process to be at high voltage,
must be grounded. Grounded conductive
flooring must be provided in the spray area.
Always turn off the power supply prior to
flushing, cleaning, or working on spray
system equipment.
Unless specifically approved for use in hazardous
locations, all electrical equipment must be
located outside Class I or II, Division 1 or 2
hazardous areas, in accordance with NFPA-33.
